Struct CacheMetadata

}

Fields

created_at_unix_secs: Option<u64>

Seconds since the Unix epoch when safe-migrate sync assembled this baseline. None represents a cache written before provenance support.

source_database: Option<String>

PostgreSQL database name only; connection credentials and host details are deliberately never stored in a cache.

source_role: Option<String>

Session role used when the cache was synchronized. This is needed to resolve PostgreSQL’s special $user search-path entry.

source_session_role: Option<String>

SESSION_USER at synchronization time. This remains distinct from source_role when the connection has selected another effective role.

source_search_path: Option<Vec<String>>

Parsed search_path setting before PostgreSQL expands $user.

source_lock_timeout_ms: u64

Effective lock_timeout observed on the fresh synchronization connection, normalized to milliseconds. PostgreSQL uses zero to mean that the timeout is disabled.

source_statement_timeout_ms: u64

Effective statement_timeout observed on the fresh synchronization connection, normalized to milliseconds. PostgreSQL uses zero to mean that the timeout is disabled.

schemas: Option<Vec<String>>

Explicit schema scope passed to sync. None means all non-system schemas were requested.
